ASPE Ultra automatic solid phase extraction instrument Introduction
ASPE Ultra series automatic solid-phase extraction instrument is an automatic pre-treatment equipment designed for the analysis of organic pollutants in water samples such as domestic drinking water, tap water, source water, surface water, and sewage.
This product can automatically complete the filtration, activation, sample loading, leaching, drying, elution, concentration and volume adjustment, volume adjustment and other operations in the large volume water sample pretreatment process, and can be applied to various water quality testing laboratory pretreatment The purification and enrichment process is completely automated without the need for long-term attendance by the experimenter, avoiding the contact of the experimenter with toxic reagents, and easily creating an intelligent and safe water quality pretreatment laboratory. Features
Good sample processing parallelism
1. Completely independent pump valve system
Completely independent pump and valve system to ensure that all pre-processing steps of multiple samples processed at the same time run without interference with each other, to ensure that the processing environmental conditions and instrument conditions of all samples are completely consistent, and to avoid other experimental factors affecting the parallelism of sample processing
2.Plug-type sealing method
The plug-in solid-phase extraction column sealing method seals the solid-phase extraction column at a low point to ensure that no air in the column affects the liquid sample passing through the column. The speed of liquid sample and solvent passing through the packing is precisely controlled, and its speed is not affected by the sample's own conditions. Effect, effectively guarantee sample parallelism
Effectively avoid experimental environmental factors affecting the sample
1.Light-proof housing design
The instrument is designed to avoid light, which effectively avoids the influence of the laboratory lighting environment on the unstable sample.
2.Negative pressure type concentration chamber
The design of the negative-pressure concentration chamber ensures the vacuum environment of the concentration process, and avoids the condensate produced by rapid concentration entering the sample when the laboratory humidity is too high, which affects the detection of the test object
Multi-functional and targeted
1.Integrated membrane column design
The instrument is compatible with solid-phase extraction columns of different specifications such as 1mL, 3mL, 6mL, 12mL, and 20mL; it is also compatible with solid-phase extraction membranes of different specifications such as 25mm and 47mm; the equipment can be used in various water quality testing standards
2.Online dehydration of anhydrous sodium sulfate
Can be loaded with a conventional commercial anhydrous sodium sulfate column, and the eluted sample can be dewatered online.
3.Multi-row collection design
Multi-row collection setting of eluent can be completed to meet the needs of experimenters for new method development and exploration
4. Solvent replacement function
During the concentration process, solvent concentration can be replaced automatically, and the added solvent can be set and selected. Technical Parameters
